Whether we look at capitalism, taxes, business, or government, the data show a clear and consistent pattern: 70 percent of Americans support the free enterprise system and are unsupportive of big government.

The truth is that relative income is not directly related to happiness. Nonpartisan social-survey data clearly show that the big driver of happiness is earned success: a person's belief that he has created value in his life or the life of others.

There is nothing inherently fair about equalizing incomes. If the government penalizes you for working harder than somebody else, that is unfair. If you save your money but retire with the same pension as a free-spending neighbor, that is also unfair.

In my book I don't just demonstrate that free enterprise is the most efficient way of organizing an economy - which it is. I also show that it's an expression of American values, and, thus, that a fight for free enterprise is very much a fight for our culture.
